WebThat 'superhero' feel also comes through in iridium's resistance to corrosion. We're used to gold and platinum as the exemplars of metals that stay pure, but iridium fights off corrosion better than either. It was partly for this reason - and the metal's sheer hardness - that iridium was first put to use in alloys to make the tips of fountain pens. WebGlobe Metal® recycles and reclaims all forms of raw materials and scraps containing precious metals (gold, silver, palladium, rhodium, platinum, iridium, and ruthenium).

WebRhenium also has one of the highest modulus of elasticity among all metals, second to only iridium and osmium. As the temperature increases from room temperature to 725 ° C, rhenium’s modulus only decreases about 20%. This property allows for filaments made with pure rhenium to have excellent mechanical stability and rigidity.
WebJan 1, 2010 · The kinetics of rhenium segregation follows uphill diffusion, and the diffusivity of rhenium in copper at 400°C is estimated to be 1.5 × 10-17 cm2/s. View Show abstract WebIt is usually extracted from the flue dusts of molybdenum smelters. The name Rhenium originates from the Latin word 'Rhenus' meaning "Rhine" after the place of discovery. 47 Ag 107.868200000 Silver. See more Silver products. Silver (atomic symbol: Ag, atomic number: 47) is a Block D, Group 11, Period 5 element with an atomic weight of 107.8682.
WebInstead of plated silver for the electrical contacts, try rhenium plating instead. It is harder than silver, a good electrical conductor, and does not readily oxidize at room temperature. If physical surface wear is not an issue, rhodium plating would probably work as well. Dale …
